ABSTRACT OF THE INVENTION A method for producing polymers with narrow molecular weight distribution which involves combining (1) an initiator component of the formula Image in which R1, R2 and R3 are alkyl, aryl, or aralkyl groups, and can be the same or different, and X is an acetate, an etherate, a hydroxyl group, or a halogen, and i is a positive whole number, (2) a Lewis acid of the formula MXn in which M is titanium, aluminum, boron, or tin, X is a halogen, and n is a positive whole number less than 7, (3) an electron donor component having an electron donor number of from at least about 25 to no more than about 50, (4) a solvent for the preceding and (5) a cationically polymerizable hydrocarbon monomer component. - 1 -
